Congress is in recess next week. Which means political observers will be closely watching what sort of backlash, if any, Senators face at home in the wake of their No vote on the Toomey-Manchin compromise on expanded background checks — particularly since new signs are emerging that the gun debate isn’t over.

Along these lines, Quinnipiac has released a remarkably detailed set of poll numbers out of Pennsylvania that tell us a good deal about the strengths and weaknesses of the chances for further action. It finds that 70 percent of Pennsylvania voters are either dissatisfied or angry over the Senate’s rejection of the background check compromise. That includes a majority (52 percent) of Republicans.

Pennsylvania is an interesting test case with broader implications. While it does lean blue, it has a deep gun culture, and it is home to the sort of suburban district — represented by Republicans — where gun reformers still hope to pick up unexpected GOP support.

Indeed, one notable finding is that Pat Toomey’s approval rating is now at 53 percent among suburban voters — in a state where the Philadelphia suburbs are key to statewide races. Hopefully other Republicans who represent rapidly suburbanizing states (such as Kelly Ayotte) or suburban House districts will take note. Overall, fifty four percent in Pennsylvania — and 56 percent of suburbanites — view Toomey more favorably because of his stewardship of the bill. And 61 percent of women — a demographic the GOP needs to improve among – view him more favorably.
